Hardware rv670 AGP using git mesa/ddx/xserver. Problem exists with kms using both agp and pcie gart. Does not occur with ums (using pcie gart to enable uts) Also confirmed and fixed by reverting above for another user on #radeon with a rv770 using non git xorg 7.x. Seems to affect bgra uploads - swrast mesa demos eg gloss and gears and mplayer -vo x11, others reported flash video corruption. Example of gloss corruption attached - the corrupted bands were always in the same place, but their content changed by other drawing eg. hovering mouse over window buttons to make tool tip appear.

Same thing here, with a RS780. The bug is most easily observed while playing flash videos here. The controls of various flash players are garbled and unusable. Reverting 49c458e544ae14514209ed80ea6829ca1b18ddf0 solves the problem.
(In reply to comment #0) OK now it's reverted in drm-next, although inthe case of these issues the commit message for the revert should be - seems to have some side effects in the kms cases. Rather than seems to have some side effects in the non-kms cases.
